Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications to ensure proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a specific 57.737 MHz frequency. Consider the small 2.0x1.6 mm package size for space-constrained designs. Verify that LVCMOS output levels are compatible with the receiving logic inputs of the application circuit without requiring additional level shifting or buffering components.
Part Context
This part belongs to the Mercury Electronics SMD oscillator series designed for surface-mount applications. The manufacturer specializes in quartz-based frequency control products including crystals, oscillators, and filters. This specific model represents a standard XO variant optimized for compact electronic devices requiring stable timing signals.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching frequency, voltage, package, and output logic specifications from alternative manufacturers.
